Rather sad u didn't mention the type of control. Do this by responding to the event that is called anytime the items in the control change. Just loop through all the items in the control and get the maximum width to the lengthiest string.

I do not use any control.
I do want to calculate using data from one sheet in Excel and printing the results to another sheet. Then I do want to change the cellsize to make it fit to it's contains.
So what I want to do is implement the same function which you get by sizing a column to optimal size in Excel.
And because I do not know which strings or integers will be copied to the sheet (meaning as result) I do want to print the data to the sheet and change the size afterwards.
Thanks.
Stephan.

I found a solution. To get the optimal size of the cell in Excel via VBA you have to use the .autofit operation
syntax
Columns(index).Autofit
This is the easiest solution!

Reply to what? You haven't given us code snippet of how your sending this message and, therefore, nothing to help you with. But, my first 2 questions would be:
Are you using any publicly available SMS server sites to actually send the message?
Does the site work with the mobile service you're using?

Hi ,
I have a requirement in my application where in a list of
properties are show in the property grid control.
The senario right now is , i use the property grid control
provided in .net to show a set of properties by creating a
class with private members and defining their get set
methods and assigning the object of the class to the
property control's selectedobject thus creating the
property grid, going 1 step further i would like to add
more properties to this control at runtime depending on
certain values fetched from the DB, as i cannot add members
to the class at runtime i am looking at alternative
solution to do so.
Thanks in advance.

Hi, I used open file dialog control in vb.net. I used the .InitialDirectory property to open the file folder and set to Application.ExecutablePath. I found that when it start the first time it browse at the C:\Program Files... something like that. But my purpose it open the first is the My Document folder. I don't know the code that it write, could any one give me some idea about that???

Kind of complicated because you have to get the location of the My Documents folder from the shell. The following is the code for a simple form with a single brows button that finds the My Documents folder and opens a file dialog to that folder.
You should break out the shell code into a module so you can reuse it. I just included it in a form so you can cut and paste until you understand how it works. Create a form, add a button - btnBrowse and a FileDialog control, and the add the code as follows:

Thanks, did not know about the Environment class. NET 2002 contains no support for the folder browser, so I accustomed to doing everything with the the shell APIs.

Check out my post[^] in response to the other poster. I think you'll find the code MUCH easier...

Hi can any one help me?
I have got a varible length array and need to find out its length. The way I have made the array is
dim Array() as string
Redim Array(Varible)
Thanks for any help on this.
|
|
|
|
|
By length, do you mean how many items it contains or the total number of all characters in all items in the array?
|
|
|
|
|
I mean the total number of items in the array
Thanks
|
|
|
|
|
If you want to get the number of items present in the array you can use UBound(ArrName)
|
|
|
|
|
you defined your array by redim.
In there you assigned the size by using the variable.
I would check the variable to get the size of the array
note that indexing starts at 0, so if you assign 5 to the variable, the size of the array is 6.
So in general: The size of your array is "variable+1".
I hope I did not missinterpret your question! 
Stephan.

Hi every one
I have a little problem with this issue. I have a Crystal Report Document with parameters (You know every time when you open it, With Crystal Report, a paremeters appears), When I try to open it using VB.net the parameters popup screen shows. My question is
How can i put the parameters into the code in vb.net for disable the parameters popup screen ?
Thanks
This is my code for the parameters. (doesn't work)
Dim paramFields As New CrystalDecisions.Shared.ParameterFields<br />
Dim paramField As New CrystalDecisions.Shared.ParameterField<br />
Dim paramRange As New CrystalDecisions.Shared.ParameterDiscreteValue<br />
<br />
paramField.ParameterFieldName = "FromDates"<br />
paramRange.Value = "01/01/2005"<br />
paramField.CurrentValues.Add(paramRange)<br />
paramFields.Add(paramField)<br />
<br />
Me.CrystalReportViewer1.ParameterFieldInfo = paramFields

Hi
I am currently trying to open an excel file using System.Diagnostics.Process.Start("ExcelFileName").
It works correctly in general, but if the installed machine
has excel 2000, it opens excel but the file never opens
and the cells are empty. Is this a bug with Office 2000?
What can be done?

Hi,
I am trying to create a form with the following
attributes:
1. A sizable border
2. Close button
3. No icon in the upper left hand corner
All of this can be accomplished using the Sizable
FormBorderStyle, but the icon remains. Does anyone know how to do this?
Sumit Domyan

IIRC, since the form is sizable, you can't get rid of the icon using properties. I think your going to have to owner draw the title bar of the form. I DON'T have any example code, nor do I know of any. But, in theory, it's possible to do. Look into overriding WndProc and handling the WM_NCPAINT message.

What if form is not resizable?

The only ones that support no icon in the upper left corner are the ToolWindows and None borders.

If you just don't want to see an icon, the simplest way is to just create a transparent 16x16 icon file and select that for the form's icon. Of course the title will still be offset the same, and the drop down menu will appear if the user clicks in the space.
If you want to get rid of all those, you'll have to custom draw the title area. But if you just want a no icon appearance, a transparent icon is far easier.
